Goryeo and the Great Song Dynasty are not related to the clan and the Great Song Dynasty now, since they are not the vassal states of the Great Song Dynasty, unless there is a major matter to negotiate, there is naturally no need for them to enter Beijing!

Generally, the vassal states of the Great Song Dynasty came to Beijing to pay tribute, and the Great Song Dynasty inevitably had a large number of gifts to be rewarded, and these rewards were basically several times or even dozens of times the tribute paid by those vassal states. Pen & Fun & Pavilion www.biquge.info Although this Goryeo Kingdom is not a Great Song Dynasty, if it really comes to Beijing with gifts, the Great Song Dynasty court loves face, and it is indispensable to return the reward, which is generally a loss for the Great Song Dynasty. This vassal state pays tribute and rewards, and it can also fall into the gratitude of a vassal state to the suzerain, but this Goryeo country is not even a vassal state, and the Great Song Dynasty is naturally unwilling to reward him.

Therefore, the Great Song Dynasty court was reluctant to come to Beijing for the envoys of the Goryeo Kingdom most of the time. Generally, both sides don't take each other very seriously, just talk about it in Dengzhou. Unless the Goryeo Kingdom was willing to restore the suzerain-vassal relationship with the Great Song Dynasty and other major events, there was really no need to let the Goryeo envoy enter Beijing.

It is not difficult to contact the Goryeo envoy on this errand, but for Zhong Hao, it is an errand to increase his qualifications, as long as he does not make mistakes, it can be regarded as a political achievement. That Zhong Hao has nothing to resist.

Moreover, Zhong Hao listened to Wang Yan's meaning, the reason why the official family sent him to Dengzhou to deal with the Goryeo envoy was because he was the most optimistic among the official family in this science and technology scholar! It is out of their own cultivation and importance that the official family arranges errands for themselves. Therefore, Zhong Hao was naturally happy to take on this errand.

At that moment, Zhong Hao went to the official family and told him that he was willing to accept the send!

When the official family heard that he was willing to go to Dengzhou, they gave him a face-to-face lecture, and then asked Wang gradually to accompany Zhong Hao out of the Zichen Hall and to the political hall that was also in the forbidden.

Wang gradually conveyed to the government hall that the official family sent Zhong Hao to Dengzhou to contact the Goryeo envoy, and the government affairs hall issued a letter of appointment to Zhong Hao to go to Dengzhou to receive the Goryeo envoy!

After Zhong Hao received the letter of appointment, he went out of the palace and went to Honglu Temple.

The official offices of the Great Song Dynasty set up stacked bed frame houses, and many of the official offices were set up with overlapping functions, in fact, a yamen could do it, but in the Great Song Dynasty, there were often two or more yamen divided powers, which was also a major feature of the officialdom of the Great Song Dynasty.

For example, there is overlap between the Ministry of Officials and the Court of Judges, the Ministry of Household is vacated by the three divisions, and the Ministry of War is vacated by the Privy Council. When it comes to foreign affairs, some of the functions of the Ministry of Rites and Honglu Temple naturally overlap.

Many people of insight have quickly seen the disadvantages of this official office stacked bed frame house, for example, in the Qingli New Deal, Fan Zhongyan proposed to streamline the official office. It's just that this really involves the interests of too many vested interests, and in the midst of many opposition, it is still stranded.

After all, with this streamlining of institutions, there will definitely be countless redundant officials who have nowhere to place, and it is no wonder that these people do not oppose it. They all belong to the upper strata of society and are powerful, and this opposition is naturally very powerful.

However, some of the functions of the Ministry of Rites and Honglu Temple in foreign affairs overlap, but this part of the function of the Ministry of Rites in foreign affairs is not completely overhead without Honglu Temple, and still exercises some functions. This is slightly stronger than the fact that the military department and the household department have been completely used as a place to raise idlers.

Honglu Temple and the Ministry of Rites are basically in charge of this foreign affairs. Basically, when sending envoys abroad, it was a matter for the Ministry of Rites. When receiving envoys from foreign domains, Honglu Temple is in charge.

Although Zhong Hao's errand was to go to Dengzhou to meet with the Goryeo envoy, it was definitely not an envoy to a foreign country, so he naturally would not go to the Ministry of Rites. Although this errand is to Dengzhou, it still belongs to the category of receiving foreign envoys, but the place of contact is in Dengzhou, so naturally I want to go to Honglu Temple.

After Zhong Hao and Honglu Temple explained their errands, Honglu Temple sent Zhong Hao an interpreter who spoke Goryeo and two retinues to accompany Zhong Hao when he left Beijing.

Zhong Hao couldn't help but feel a little depressed, his first errand after passing the Jinshi exam was really a little shabby, and he didn't even have a guard of honor, so he sent himself two attendants and a translator!

Of course, the imperial court arranged it like this, and it seems that it really doesn't care much about this errand. This can also make Zhong Hao more comfortable!

Zhong Hao also plans to stay in Qingzhou for a while longer, he hasn't seen Wan'er and his aunt for almost three years, how can he reunite for a while, this errand doesn't matter, he can just take care of himself!

According to officials at Hongroji Temple, the Goryeo credentials stated that their envoy had arrived in Tengju in early May. Zhong Hao estimated that he had just arrived in Qingzhou in early May, so why did he have to stay for a while before he could go to Dengzhou, since the imperial court didn't care much about this errand, he could just follow his own arrangement and stay in Qingzhou for a while before going to Dengzhou.

Zhong Hao felt that even if he asked the Goryeo envoy to wait for a while, he would probably not have any problem going to Dengzhou to contact him again.

………………

Before Zhong Hao left, he went to the glasses workshop and shochu workshop prepared by Pan Xu, and stayed for several days.

Zhong Hao is about to leave the city of Tokyo, so he naturally wants to take advantage of his time in Tokyo to teach the craftsmen in the workshop the skills of making clairvoyants and glasses, as well as the skills of distilling shochu!

The production and installation technology of this clairvoyance is not difficult to say, it is nothing more than an eyepiece and an objective lens, one is a convex lens and the other is a concave lens, so that the combination forms a magnified scene.

Of course, this technology is easy to say, but it is still quite difficult to operate.

First of all, the radian of the grinding of the convex lens and the concave lens must be required, and only the appropriate radian can achieve a better imaging effect. How to install and combine the eyepiece and the objective lens also requires some experience. If the angle and distance are not suitable, the clairvoyance is likely to be useless at all.

Of course, in order to adjust the distant view of the scenery, the copper tube of the clairvoyant should be telescopic, so that the telescopic of the copper tube can be used to adjust the distant and near scenery to be seen.

As for glasses, in fact, it is the same as clairvoyance, or the principle of using lens imaging. These myopia glasses and reading glasses are nothing more than the difference between two lenses, a concave lens and a convex lens.

Of course, if you want to wear these myopia glasses more suitably, you also need to determine the power of the lenses according to the wearer's myopia degree! As for reading glasses, it is natural to determine the best lenses for the wearer according to the prescription, but compared with myopia glasses, these reading glasses have slightly lower requirements for prescription.

But obviously, with Da Song's current technology, it is difficult to determine the accuracy of the wearer, and it can only be roughly determined according to the wearer's myopia, to install slightly thicker lenses or slightly thinner lenses.

The various procedures and problems that may be encountered in the production and installation of this clairvoyant, in fact, the craftsmen of Jingqiang Village have already had relatively detailed work notes under the stimulation and strict requirements of Zhong Hao's bonus, as well as the detailed experience summarized according to these work notes.

Therefore, Zhong Hao taught those craftsmen the production and installation techniques of clairvoyance, and he was naturally familiar with the road, and it was easy to teach the techniques of these thousands of miles to the craftsmen of the Pan family.

But the grinding and installation of these glasses really had to be studied from scratch with the craftsmen.

The curvature of the lenses, the grinding of the lenses, and the angles required to mount them on the copper frames, all of which were studied by Zhong Hao and the craftsmen of the Pan family.

Because when he was in Jingqiang Village, this clairvoyance had only been done in research and summed up a lot of experience, but this glasses had never been developed, and Zhong Hao needed to explore it from scratch.

Fortunately, with the experience of making and grinding various convex lenses and concave lenses summed up in the production of clairvoyance, there are many things that can be used for the grinding of spectacle lenses. Therefore, the craftsmanship of making these glasses was quickly mastered by Zhong Hao and the craftsmen of the Pan family.

Through a certain amount of exploration, Zhong Hao set three rough standards for the thickness of myopia lenses: thin, medium and thick. At that time, there will be glasses for literati with different degrees of myopia.

Of course, such a rough standard for myopia spectacle lenses is likely to affect the eyes of those literati who wear glasses. But there is no way, there is no optometry instrument now, and Zhong Hao has no optometry standards, so he can only settle for it first.

In any case, at least with this myopia glass, it is already good to let these literati who are troubled by myopia see things clearly. It is conceivable that these myopia glasses will be very popular with those literati with poor eyesight.

As for some specific standards, they can only be summarized and formulated slowly in the subsequent time.

Zhong Hao told Pan Xu some of his ideas about the production and sales of these glasses, and asked him to summarize the experience of glasses with those glasses sales and production personnel. For example, if someone comes to wear glasses in the future, they can test their vision with an eye chart, and then decide the thickness of the lenses according to their eyesight.

Pan Xu is also a talent in this business, as soon as he heard Zhong Hao say this, he immediately understood, and he agreed with Zhong Hao about these things.

As for the shochu workshop, when it was being prepared, Zhong Hao often came to guide its construction. The sanitary facilities, exhaust facilities, and the erection of the pot in this shochu workshop were all designed by Zhong Hao.

When the soju workshop is built, Zhong Hao only needs to tell the servants of the Pan family who are working as workers about the skills of distilling liquor, and it is relatively easy to get on the track.

Pan Xu couldn't help but be amazed and sighed when he saw that his servants who were working as distillery workers could easily distill soju that was as clear as water and as strong as fire under Zhong Hao's knowledge.

Pan Xu couldn't help but ask Zhong Hao in surprise: "Wen Xuan, this fiery soju is so easy to make?!" ”

Zhong Hao smiled: "It's really that simple! ”

Pan Xu asked, "Isn't it said that it needs to be steamed and brewed nine times before it can be purified to such a mellow and strong soju?" ”

Zhong Hao said with a smile: "If this wine wants to be sold at a high price, it is natural to say that the process is more complicated, anyway, others don't know how to make such a strong liquor." Second brother, if we want to make better money, we need to continue to publicize how complicated this wine brewing is! ”

Pan Xu smiled: "Hehe, you don't need to mention this, Wen Xuan, the second brother naturally knows it!" After a pause, Pan Xu couldn't help but ask again: "This process is so simple, why are there so many wine shops in the Great Song Dynasty, but no one has ever figured it out?!" ”

Zhong Hao spread his hands and said with a wry smile: "I don't know about this matter, the second brother's problem is too deep." ”

Pan Xu smiled: "Wenxuan is still as funny as ever." However, it has been thousands of years since the invention of this wine, and the predecessors have never seen through this process, but Wen Xuan has seen through it, Wen Xuan is really a strange person! ”

Zhong Hao said in his heart, let Pan Xu say this, he really felt that this person who invented the distillation and brewing technology was a strange person, and he really admired it. Of course, in fact, many inventions in this history have been inadvertently tested, not necessarily because much research has been done on this technology.

Zhong Hao was a little embarrassed by Pan Xuyi's words, and said very modestly at the moment: "The little brother is not a strange person, the little brother just saw it by chance on an ancient book that he treasured in his own collection." ”

Pan Xu couldn't help but flicker his eyes when he heard this: "Which ancient book is it?" Did the ancients already know that this distillation method could make high-grade liquor? ”

Zhong Hao spread his hands and said: "I can't remember clearly, my younger brother read a lot of books when he was young, and I forgot which ancient book I saw it in." ”

"What about your ancient books?"

"Washed away by the flood......"

"Uh......" Pan Xu remembered that it seemed that Zhong Hao was attached to Qingzhou! It seems that he was born in Lanzhou, and later he and his family were washed away by the flood before they were exiled to Qingzhou. The home has been washed away, and this ancient book must be gone.

In fact, the reason why Pan Xu asked about this ancient book was not that he was suddenly interested in books, he was afraid that other people's families also had this ancient book, and if others also discovered the secret method of this soju, then his family's soju business would be affected.

At that moment, Pan Xu asked Zhong Hao again: "Then Wenxuan, will others have this rare ancient book in your house?" If others have it, then wouldn't our secret method of soju be spied on by others! ”

Zhong Hao said in his heart: How can there be any ancient books, they are simply nonsense by themselves, you guy is still serious!

At that moment, Zhong Hao reassured Pan Xu and said: "My family's collection of ancient books are all handed down by my ancestors. According to the ancestors, this ancient book outside should have been lost for a long time, and no one should find this secret method of brewing shochu from it! ”

Pan Xu listened to Zhong Hao's words, and then he was relieved.

………………

Zhong Hao is going back to Qingzhou Province, and Yang Huaiyu is also going back to Linzhou, this time goodbye, I don't know when I will see you again.

Yang Huaiyu couldn't help but be a little reluctant, the two have been together all day for more than two years, and the brotherly love is still very deep.

In the past few days before Zhong Hao left Tokyo, the two of them really had a good time.

Zhong Hao wants to take Fu Ruozhu to Qingzhou, and he inevitably has to go to Fufu to resign. When he was in Fufu, Feng Jing also gave a lot of suggestions for Zhong Hao's dispatch this time.

At the end of the month, after the affairs in Beijing were stopped, Zhong Hao and Xu Feng embarked on the journey back to Qingzhou with Xu Feng under the farewell of relatives and friends such as Yang Huaiyu, Pan Xu, Lu Qi and Feng Jing.
